The digital negative of an image can be given as, s = (L-1)-r

Where s is output pixel value, r is input pixel value and L-1 is maximum pixel value.

For 8 bits per pixel image maximum pixel value is 255.

Thus the digital negative of the image is,

134	50	38	99	104
116	128	98	138	130
3	138	19	117	113
28	73	77	58	13
54	149	136	4	15
